Abstract

A rail and bracket integrated wall-attached supporting device, and a wall-attached supporting seat thereof and a jacking method therefor. The wall-attached supporting device comprises wall-attached supporting seats (3), wall-attached connecting pieces (2), and guide rail upright columns (4), and the wall-attached connecting pieces (2) are pre-buried in a concrete wall; each wall-attached supporting seat (3) comprises a bottom plate (3.7), supporting claws (3.12), supporting lug plates, and a lateral shift-resistant guiding mechanism; the supporting lug plates are fixed to one side of the bottom plate (3.7); the supporting claws (3.12) are supported on the supporting lug plates and rotatably connected to the lug plates, and can flip over freely; the supporting claws (3.12) are used for supporting force bearing bars (4.2) on the guide rail upright columns (4); the lateral shift-resistant guiding mechanism comprises inner lateral shift-resistant guiding wheels and outer lateral shift-resistant guiding wheels (3.2) which are mounted on the bottom plate (3.7) and clamp a T-slot guide rail (4.1) of the guide rail upright column (4) in a rotatable manner. The jacking method comprises mounting the wall-attached connecting pieces (2) and the wall-attached supporting seats (3), and respectively hanging the guide rail upright columns (4) and cylinder supports (5) on the supporting claws (3.12) of the wall-attached supporting seats (3) of two adjacent layers. Piston rods of hydraulic cylinders (6) mounted on the cylinder brackets (5) are fixedly connected to the bottoms of the guide rail upright columns (4) and jack the guide rail upright columns (4); after jacking is completed, the force bearing bars (4.2) on the guide rail upright columns (4) fall back and are hang on the supporting claws (3.12) of the wall-attached supporting seats (3) of a higher layer, and the piston rods of the hydraulic cylinders (6) are retracted to drive the cylinder brackets (5) to be elevated by one layer and then fall back and be hang on the wall-attached supporting seats (3), thereby completing one jacking process. The jacking device is flexible in mounting and dismounting, and has lateral shift-resistant guiding performance.

Abstract

A full-circle secondary lining inverted arch construction formwork system for a long-distance tunnel and a formwork transporting method adopt a customized steel formwork, a steel pipe support, and a turn buckle. The steel pipe support is arranged on the longitudinal main edge, and is provided between the longitudinal rails and a primary lining for supporting vertical buoyancy. The turn buckle is arranged between two sides of the formwork and a reserved steel bar for resisting horizontal load generated during asymmetric pouring. A cantilever gantry crane and a transportation flat car are used for formwork transporting, wherein travel rails of the cantilever gantry crane and the transportation flat car are integrated on the customized steel formwork, and there is no other rail. According to the present, the formwork has high strength and rigidity, the formwork system is simple.

Abstract

A rapid construction method for a secondary lining of a small-section tunnel includes steps of: transporting and store secondary lining steel bars to a designated position in the tunnel with a steel bar transport vehicle and a wheel type dump truck; after the tunnel is cleaned, simultaneously constructing the secondary lining from two ends to a middle of the tunnel; constructing a lower inverted arch with a customized inverted arch formwork and then constructing an upper arch wall with a plurality of portal arch wall formwork trolleys; wherein the portal arch wall formwork trolleys form a set, and are connected by hinges, so as to construct in a curve tunnel. The rapid construction method has a long single construction section, and procedure connection is compact, thereby realizing rapid and efficient construction of the secondary lining.

Abstract

A construction building equipment includes hanging pedestals, sleeve frames, hydraulic cylinders, upper reversing boxes, lower reversing boxes and track columns. The multiple hanging pedestals are fixed on an outer side of a shear wall of an external wall. The sleeve frames and the track columns are clamped on the hanging pedestals. The sleeve frames are clamped on outer sides of the track columns. The lower reversing boxes are fixed at upper ends of the sleeve frames. The hydraulic cylinders are connected with the upper reversing boxes and the lower reversing boxes. Side surfaces of the track columns are provided with pane holes for cooperative climbing of the upper reversing boxes and the lower reversing boxes. Upper ends of the track columns are fixedly connected with a top platform. Hangers and formworks are suspended on the top platform through booms.

Abstract

A temperature adaptive construction lift with counterweight segmented unloading and an implementation method, an unloading attachment frame being arranged on a secondary guide rail frame at every one or more standard sections along the vertical direction, a counterweight being arranged on one end of each unloading attachment frame, and the other end being secured to a vertical structure spaced apart from the secondary guide rail frame, the unloading attachment frame clamping the secondary guide rail frame from the periphery; the bottom part or a lower position of a primary guide rail frame is rigidly secured onto the vertical structure or the ground or the foundations; the primary guide rail frame and the secondary guide rail frame are fixed together by means of connecting rods, and the counterweights are connected to the connecting rods by means of a traction rope pulley mechanism. The present construction lift and implementation method can unload the dead weight of the guide rail frames in a segmented manner to relieve temperature stress, solving the problem in guide rail frames of traditional construction lifts of the high internal stress on the guide rail frames due to the high mounting height and large temperature changes, so that the lifting height of the construction lift is not restricted.
